A system performance evaluation method and device

Abstract

The present invention relates to the field of communications. Disclosed are a method and device for assessing system performance, for use in implementing performance of a dynamic simulation assessment while achieving efficiency of a static simulation assessment. The method is: rendering as a dynamic-static interface of a semi-static simulation a corresponding relation between a static indicator value and a dynamic indicator value assessed via a dynamic pre-simulation scheme, acquiring an air interface performance parameter of a UE via an output volume of a static simulation, mapping the air interface performance parameter to the dynamic-static interface on the basis of a certain mapping method, and acquiring a related output volume of a dynamic simulation. This implements the performance of the dynamic simulation assessment while achieving the efficiency of the static simulation assessment, that is, under the premise of improving the efficiency of the simulation assessment, a time-varying characteristic of a channel is embodied via the result of the simulation assessment, also processing gains of algorithms of transmission mode and detection algorithm, thus ensuring the performance reliability of the simulation assessment, and conserving processing time required by the simulation assessment.

Description

technical field [0001] The invention relates to the communication field, in particular to a system performance evaluation method and device. Background technique [0002] At present, when the existing LTE (Long Term Evolution) network planning software is used to evaluate network performance, static simulation or dynamic simulation is mainly used, and static output or dynamic output is directly calculated or mapped to the link curve. Get the estimated performance of the system. Among them, the so-called static simulation refers to: multiple captures of the mobile communication system scene, and the establishment of an ideal system balance point according to the results of each capture, and then statistics of the performance of the system when the ideal balance is reached, simulating the average performance index of the system; The so-called dynamic simulation is a discrete event simulation method, which simulates in a certain cellular network topology, user terminals move a...

Problems solved by technology

[0003] However, the static simulation method and the dynamic simulation method have their own imperfections. The former simulation efficiency is relatively high, but it does not fully consider the time-varying characteristics of the channel and the gains brought by various physical layer algorithms, while the latter is more reliable. accurately reflects the network performance, but the simulation efficiency is low

In view of this, under the existing technology, in the system simulation evaluation, in order to improve the simulation efficiency and the impact on the system performance is within the acceptable error range, technicians expect to be able to design a simulation method that can achieve static evaluation efficiency At the same time to obtain dynamic evaluation performance, however, at present, there is no simulation method that can well achieve the expected goal
